What you could do is make all other paths a standby path and, in case of a failure, use the alternate path. However, the trick is getting backup software to use the alt path and perform all the related error recovery in a failure mode. In the vast majority of cases backup software will fail the entire job if the the tape device is marked as failed. You'd have to change it to ping the available paths from time to time and try to restart automatically to get any benefit from alternate paths to the tape device. _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
